Hi I think I have a really dumb question. But I captured some traffic and than went to protcol hierarchy statistic. What I dont understand know how can IPv4 have less percent bytes than TCP? IP4v shows 3,7% and TCP 95,7% and so the number of bytes in TCP is much higher than in ipv4. I thought that TCP is in IPv4. So data+tcp+ip and without IP I thought to have less bytes (only data+tcp)

Basically, the statistics is only counting the packet bytes associated with each layer and not the payload of each layer.

To understand the implementation better, it may help to go back to Bug 1885. I disagreed with the implementation back then (as noted in Comment 4), and I still disagree with it today.
